Mediarq.Testing

Test harness for Mediarq: a SpyMediator that records every dispatched request/notification while still running them through the real pipeline (handlers, validators, behaviors — nothing is faked), plus ready-to-use FakeClock/FakeUserContext.

dotnet add package Mediarq.Testing

Spying on dispatch

services.AddMediarq(isHttp: false, typeof(Program).Assembly); // your normal registration
services.AddMediarqSpy();                                     // decorates IMediator

var sender = provider.GetRequiredService<ISender>();
await sender.Send(new CreateOrder(customerId));

var spy = (SpyMediator)provider.GetRequiredService<IMediator>();
spy.HasSent<CreateOrder>().Should().BeTrue();          // any assertion library works
spy.Published<OrderCreated>().Should().ContainSingle();

AddMediarqSpy() decorates the already-registered IMediator — call it after AddMediarq/AddMediarqCore. ISender and IPublisher are covered too: both already resolve the current IMediator from the container, so every Send/Publish/CreateStream call is recorded no matter which of the three interfaces the caller depends on.

In a smaller test, construct one directly instead of going through DI:

var spy = new SpyMediator(myRealOrFakeMediator);
await spy.Send(new CreateOrder(customerId));
spy.SentRequests.Should().ContainSingle();

FakeClock / FakeUserContext

var clock = new FakeClock { UtcNow = new DateTime(2026, 1, 1, 0, 0, 0, DateTimeKind.Utc) };
var user = new FakeUserContext { UserId = "u1", UserName = "alice", Roles = ["Admin"] };

services.AddSingleton<IClock>(clock);
services.AddScoped<IUserContext>(_ => user);

Both are plain settable implementations of IClock/IUserContext — register them in place of SystemClock/HttpUserContext/DefaultUserContext in a test's IServiceCollection.
